RealBengine is the candidate of the future version of my voxel render Bengine, it is based on software ray tracing and it has 6 degree of freedom.

However, there is almost no noticeable performance improvement from NME to OpenFL. The Win32 binary still runs at 10~15 FPS, Flash target is about 5 FPS, and HTML5 target is only 0~1 FPS, so lots of optimizations are needed. I'm planning to re-implement to algorithm in LIME/GLSL shaders for a speedup.
